Event triggering

You may need to install xdotool using your package manager. This tool allows you to emulate keyboard action in different combinations, but I will need to emulate pressing the right arrow key.

How it works:

When web-cam detects movement an event emulating ‘right arrow’ key is pressed. Since I am using HTML5 DZslides from here, this allows me to move to next slide only with moving my hand in front of my webcam.

Run

Run it and move your hand in front of your camera. You may want to turn on the logging to see the motion detection and the event detection if it’s not working at first.
